Control of Monopoly・Oligopoly in IT and Public Utility industry in age of the post deregulation

特别是在欧洲和德国的法律中，考虑到在公用事业工业中引入竞争的经济放松管制，讨论了竞争法和部门管制。借此机会，“基本设施原则”的重要性显著提高。特别值得注意的是，出现了排除竞争者的问题。一般支配控制理论与基本设施理论趋于接近，具有重要意义。

Competition Law and sector regulation is dealt with, especially in European and German law as well, taking into account of the economic deregulation in which competition is being introduced in public utility industry. Taking this opportunity, "Essential Facilities Doctrine" has significantly been increasing its importance. It is particularly remarkable that the problem concerning exclusion of the competitors has been arising. It is meaningful that general dominant control and Essential Facilities Doctrine are tend to come close.
